IMPROVEMENT m CULTIVAII'ORS.

Specification forming part of Letters Patent No. 192,992, dated July 10, 1877; applicationlfiled March 10, '1877.

To all whom it may concern Be it known that I, SAMUEL N. HENcH, of

Ickesburg, in the county of Perry and State of I Pennsylvania, have invented a new and valuable Improvement in Cultivators; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawingsis a representation of a central section of my cultivator. Fig. 2 is a bottom view thereof, and Fig. 3 a detail. Fig. 4 is a bottom view of the cultivator-frame, and Fig. 5 is an end View of the same. Fig. 6 is a plan view of the cultivator. Fig. 7 is a detached perspective view of the adjustinglever, by means of which the cultivator-teeth are raised and lowered.

This invention relates to cultivators; and it consists in the construction and arrangements hereinafter set forth.

In the accompanying drawings, A designates the frame of my vehicle, B the drafttongue attached thereto, 0 the two transporting-wheels, and l) the axle.

In place of said axle I substitute two small axles or spindles, V, to each of which one of the wheels is suitably attached, turning thereon. The inner ends of said axles V are connected by link-bars o o to the ends of a yoke or double treadle, V, which is operated'by the drivers feet so as to guide the vehicle. A guide plate. or strap, V is secured to the under side of draft-tongue B, at the rear thereof, and regulates the movements of said axles. The machine then appears as shown in Figs. 4 and 5. I next attach thereto the cultivator attachment shown in Fig. 1, by passing the ends of its pivot-rod W through lugs 12. a. On this rod are pivoted the front parts of the drag-bars W of the cultivator,

the front ends it of said bars being bent vertically upward and connected at their tops by a cross-bar, 2. From the middle of said crossbar a chain, 1,0 extends backward to a hook on adjusting-lever B. This lever is provided with a lip, r, similar to 1, (see Fig. 1,) but inclined in a diagonallyopposite direction, which lip is adapted to engage with any one of a series of reversed notches, s, in plate S,

near the back part thereof. By shifting said lever from one of said notches to another the inclination and depth of the cultivator-teeth X can be regulated. These teeth or plows are attached to the rear ends of said dragbars W, or to short rigid arms W, connected thereto. On the inside of the inner lines of said cultivator-teeth are two guard-plates or runners, W which are secured to said dragbars by springs w braced by bars or stops w. These guards or runners prevent the earth from being thrown over the young plants while the machine is straddling a row of corn, and measurably protect the cultivator-teeth from injury by stones, &c. The rear ends of said drag-bars are hung by chains 20 to arms P on rock-shaft Q.

Y designates a supplemental middle dragbar, provided with two additional teeth or plows, y y, which is placed between the dragbars, previously described, upon pivot-rod W. Its front end, whereby it is pivoted, is bifurcated at y y, as shown in Figs. 3 andtfi, and it is held in proper position by the pressure of spring-plates Z against said diverging front end y y. Said spring-plates are slotted at their attachment to drag-bars W W, so as to allow a certain amount of play. When the devices are arranged as last described they are adapted to be used as a harrow for wheat and other grain.

What I claim as new, and desire to secure by Letters Patent, is I 1. The combination of pivotedadjustinglever B, having diagonally-opposite lips a" r, with locking-plate S, having notch s and reversed notches s, whereby said lever is adapted to raise the cultivator-teeth out of engagement with the ground, or to adjust them to any depth required, substantially as and for the purpose set forth.

2. The combination of drag-bars W with pivot-rod W, supplemental drag-bar Y, and spring-plates Z Z, substantially as and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
